Page 16: Setting Up The Board Configuration
ThinkLABS Setting up the Board configuration Board Description Atmega128 controller The ATmega128 is a low-power 8-bit microcontroller based on the AVR enhanced RISC architecture. The Atmel ATmega128 is a powerful microcontroller that provides a highly flexible and cost effective solution to many embedded control applications.
Page 17: External Power
ThinkLABS External power The external power connector in the above figure can also be used for connecting rechargeable batteries and making the board operate on battery power in case of robotic or other such mobile applications. Test LEDs Test LED's are pulled-up so to glow the LEDs we need to make the particular port pin Low. You can connect the General Purpose PORT to test LED Port using FRC Cable.
Page 18: General Purpose Ports
ThinkLABS USB Power (Pressed) / External power (Depressed) Refer to the uNiBoard figure where the components have been labeled to understand where these switches are physically placed on the board. While you have connected the uNiBoard cable for programming purposes or for powering the board this switch should be in the pressed position.
Page 19: Jumper Settings
ThinkLABS The PORTC and PORTF (ADC) are open ports and can be connected to test LEDs through FRC cable. These can be accessed using 10-pin the FRC connector. The pin diagram of Atmega128 is given below along with the manner in which we have utilized the port pins...
